Title: Pneumatic electric converter for alarm systems - has light sources passing light through filled photo tubes to affect current of photo transistor
Inventor: STELTER KORD
IPC: G08B13/10
Filed: 1975-09-11
Abstract: The converters are used to measure small air vol. difference displacements and convert them into electrical signals, especially for warning systems which react to pressure. A small storke at only a few micrometers, is converted into a usable electrical signal. By suitable choice of sensor tubes, large situations can be monitored and displayed by a suitable selection logic. A light source sends it light through the light tubes, all-shaped tube and light tubes to the base of the photo-transistor. When there is a vol. shift the light-darkening medium in the tubes is shifted so that the light falls fully on the transistor base and a larger current flows in the emitter circuit. A further photo tube can be used, so that volume shifts effect an interruption in the photo-current.

Title: Thermoplastic tubular film extrusion head - has flow adjusting threaded spindle axially movable in mandrel central bore
Inventor: FRITZ HANS-GERHARD DR
IPC: B29C48/475
Filed: 1975-10-10
Abstract: The head involves a housing, a feed channel and a mandrel, against which flow takes place, maintained centrally in this by holding elements so as to form a axial flow-traversable annular channel between it and the housing. The mandrel-holding elements extend axially, being located in the axial projection between the central feed channel and the annular channel and passsing through at least one annular space traversed by a radial flow, generally as disclosed in the parent Application. The design is improved by the use of an adjusting element which is axially adjustable in the mandrel and projects into the central feed channel in order to vary the cross section of the feed channel to one of the annular spaces. Advantageously, the adjusting element is screwed into the mandrel and can be regulated from the exit end of the tubular head. Design improves the flow conditions in the tube extruder head and gives better correspondence between the part streams traversing annular space through which the mandrel holding elements pass.

Title: Brushless permanent magnet DC motor - with Hall elements controlling differential amplifiers feeding field windings
Inventor: HEINZ RICHARD
IPC: H02K29/08
Filed: 1976-01-20
Abstract: In a small low inertia brushless motor, control may be effected by operational amplifiers instead of switching transistors. Hall elements at 90 deg. are associated with field windings also at 90 deg.. The Hall element output is fed through trimming resistors (15,16) to the input terminals of operational amplifiers connected in the differential mode. The resultant output is a 2-phase alternating voltage synchronised with the rotor, and is used as the supply for the field windings. Voltage and current feedback (21,25) for each amplifier gives the motor a shunt characteristic such that speed is dependent upon supply voltage. Reversal of the machine is also possible as it has the same operating characteristics in each direction.

Title: Tube post system optical scanner - has detection impulses for slugs controlled for decoding unit by timer
Inventor: OPPERMANN FRANK DIPL PHYS
IPC: B65G51/44
Filed: 1976-04-09
Abstract: The optical scanning system is for slugs transported in a tube post system, ascertaining the destinations as they are in motion. The slugs have marking rings giving their destinations behind the first guide ring. The detection impulses for the decoding unit are controlled by a timer, so that the first impulse occurs after an interval representing the time taken for the slug to pass the scanning point as far as the rear of the first guide ring, plus a shorter time interval. This is half the first interval, where the proportions of length of first slug section, interval between first guide ring and marking ring, and marking ring width are 4:1:2.

Title: Image intensifier with photocathode transmitting layer - has sections linked via high resistance and voltage drop preventing screen overload
Inventor: LIEB ALBERT DIPL ING
IPC: H01J31/50
Filed: 1976-04-15
Abstract: Image intensifier has a photo-cathode layer and a cathode electrode on the inner surface of a light transmitting photo-cathode mount. One ring shaped section of the cathode is connected to the photocathode layer and the other ring shaped section is connected to the negative pole of a direct voltage source. The second electrode section (4) is connected to the first electrode section (3) interleaved with a ring shaped insulated section (5). The surface of the first electrode section has a smaller surface area than the second. Its electrical connection to the second section is via a high resistance (R2). The other end of the first ring shaped section is connected to the negative pole of the voltage source (10) via a high cathode resistance (R1). The intense optical radiation will cause a voltage drop necessary to prevent the energy falling on the light screen (8) from exceeding its loading capacity.

Title: Combined current supply and starter for fluorescent lamp - uses reserve battery feeding through step=up static inverter when mains fails
IPC: H05B41/04
Filed: 1976-10-26
Abstract: The starter and supply circuit, for a fluorescent lamp, drives the lamp directly from the AC mains when the mains supply is operating correctly and from a reserve DC voltage when the mains fails. The DC voltage is stepped up to exceed the lamp's discharging voltage. A reserve battery is charged from the mains via a rectifier. When the mains fails the battery is coupled via a static inverter, a current stabiliser and a second rectifier to the lamp. Amongst the many advantages gas are: efficient use of battery power, short and few connection lines, no loss due to inductive ballast circuits etc.
